Reproductive frequency (?) | Iteroparous |
Reproductive type (?) | Asexual Sexual References: Sokolover, N., Ostrovsky, A. N., Ilan, M. 2018. Schizoporella errata (Bryozoa, Cheilostomata) in the Mediterranean Sea: abundance, growth rate, and reproductive strategy. Marine Biology Research, 14(8), pp. 868-882. Comments: They are predominantly multilaminar through frontal budding, often resulting in massive structures. A two-year survey of its reproductive state showed that the colonies of this species are simultaneous hermaphrodites, featuring both sterile and hermaphrodite zooids at various stages of the sexual cycle. |
Developmental trait (?) | Brooding Lecithotrophy References: Sokolover, N., Ostrovsky, A. N., Ilan, M. 2018. Schizoporella errata (Bryozoa, Cheilostomata) in the Mediterranean Sea: abundance, growth rate, and reproductive strategy. Marine Biology Research, 14(8), pp. 868-882. Comments: S. errata exhibits the most common reproductive pattern among the class Gymnolaemata, with these quential production of a few large macrolecithaloocytes, and the formation of non-feeding (lecithotrophic) larvae incubated in the protec-tive brood chamber (ovicell). |
Characteristic feeding method / Life stage (?) |
References (not structured): Tompsett, S., Porter, J. S., Taylor, P. D. 2009. Taxonomy of the fouling cheilostome bryozoans Schizoporella unicornis (Johnston) and Schizoporella errata (Waters). Journal of Natural History, 43(35-36), pp. 2227-2243. Comments: Bryozoans are suspension feeders with retractable U-shaped crowns of tentacles (lophophores) that bear cilia. The movement of cilia create small currents that bring microscopic prey (plankton) and organic particles toward the animal. The particles are then guided into the mouth by action of the tentacles and cilia. |
Mobility / Life stage (?) |

Salinity tolerance range (?) | Unknown Comments: Not available. |
Habitat modifying ability potential (?) | Autogenic ecosystem engineers References: Cocito, S., Ferdeghini, F., Morri, C., Bianchi, C. N. 2000. Patterns of bioconstruction in the cheilostome bryozoan Schizoporella errata: the influence of hydrodynamics and associated biota. Marine Ecology Progress Series, 192, pp. 153-161. Comments: S. errata is a significant environmental bioengineer, whose colonies contribute to the substrate complexity and therefore affect the biodiversity of these habitats. |
Toxicity / Life stage (?) | Not relevant |
Bioaccumulation association (?) | Unknown Comments: Not available. |
Known human health impact? | Known Comments: Harmless. |
Known economic impact? | Not known Comments: Not available. |
Known measurable environmental impact? | Known References: Sokolover, N., Ostrovsky, A. N., Ilan, M. 2018. Schizoporella errata (Bryozoa, Cheilostomata) in the Mediterranean Sea: abundance, growth rate, and reproductive strategy. Marine Biology Research, 14(8), pp. 868-882. Comments: This species is also known as a dominant spatial competitor. |
